Please tell me how to implement this.

name: Install and Configure IEM
hosts: rhel
ansible_become: yes
ansible_become_method: su
ansible_become_user: root
ansible_become_pass: passw0rd
tasks:
 
 - name: Creating masthead file path
   file: path=/etc/opt/BESClient state=directory
   
 - name: Creating install directory

Answer 1

I use :

deploy.yml

- name: Todo something
  hosts: all
  become: yes
  become_user: root
  become_method: su

When you execute the playbook pass the password as an extra var.

 --extra-vars='ansible_become_pass=password'
